5. A lot is messed-up with this.

In the first place, China only holds about seven percent of U.S. government debt.

Most of the federal government's debt is owed to Americans and to ... the federal government, i.e., Social Security.

In the second place, 'national security' payments also means contractors for things like the F-35 (a monstrous boondoggle and waste of money) and hundreds of other unnecessary military programs. It would be one thing if actually paying troops was at the top of the list, but I don't suspect that is what would actually happen -- the military gravy train for contractors and the Pentagon elites comes first.
